I have tried the 180gr speers and they shot terrible out a 300RUM and a 300winmag. I am talking 2.5MOA but they shot fast. I mean I was getting 3350fps with 94gr of H1000. No pressure signs.

I now shoot 180gr Accubonds for moose. And plan on using that for elk next year. I also like partitions and TSX. For deer, I still use bullistic tips.
